All of our solar chargers will power tablets that charge from a USB cable including: iPad (any version), Samsungs, and Kindles. The larger the solar system, the faster your tablet will be charged. Our personal favorites are the Fuse 6W or Switch with the V44 upgrade for 7" tablets and the Fuse 9W for 10" tablets.

For tablets that are not powered by a USB cable including the Microsoft Surface and Google Pixelbook, you'll need to charge your device from one of our Solar Laptop Charger. We'll go into more detail below as to why.

When charging from our battery once it is full, your tablet will charge at about the same rate as from your wall charger. The time required to collect that energy from solar depend on the capacity of the tablet's battery, the size of your panel(s) (in Watts), the weather (sunny/cloudy), shading on the panel(s), and the angle of panel(s).

On a sunny day with the panels outside, un-obstructed, and facing the sun, the 6 Watt systems will provide about 1 hour of runtime on a 7" tablet for every hour in the sun and the 9 Watt systems will do the same for most 10" tablets.

If your device charges from a USB cable (except for the Galaxy Tab), just use the cable provided by the manufacturer. The adapter for the Acer Iconia Tab is also included with all our laptop chargers. You will need an optional adapter if you have the Microsoft Surface 2 or Surface Pro 3.

The Fuse systems (as well as the backpacks and the Switch) have padded sleeves to store your tablet as well as a nicely secured spot for the Voltaic battery and any charging cables. The kits are lighter, but are not as convenient.

Yes, you can get our V15, V44 or V88 universal batteries by themselves. Here's approximately how much of a charge they will give each tablet. These are estimates based on testing many of these tablets.
